RECEPTACLE IEOBMINGI' Application led December This invention relates toimprovements in machines particularly designed for formin from preparedblanks or sheets of materia open receptacles or cartons and filling orpacking such receptacles with articles. The invention more particularlyrelates to such machines designed for use in candy factories to producethe receptacles, and to pack a predetermined number of pieces or unitsof candy therein, such candy usually being wrapped in thin sheets ofpaper before being delivered to the machine.

vIn the manufacture of certain kinds of candy it has been founddesirable, to facilitate handling in' storage, and for display invending, to pack the candy in small paper receptacles or cartons, apredetermined number of pieces or units being usually pazked in eachreceptacle. The candy to be thus packed is cut in small pieces,preferably rectangular v,in form, each piece being usually wrapped in athin sheet of paper to render it sanitary. The cutting and wrapping ofthe material or candy, as above described, is usually accomplished byautomatic machinery and forms no part of the present invention.

By present methods7 after the candy has thus been wrapped or preparedfor packing, it is distributed upon one or more packing tables where".it is manually packed into open receptacles, usually by girls employedfor that particular purpose. The receptacles are delivered to thepackers in the form of blanks which must be manually folded and formedbefore the candy or other articles can be placed therein. This method ofpacking candy repuires considerable time and labor, resulting in anincrease in the cost of manufacturing. It is, therefore, desirable thatmeans be provided whereby the receptacles may be mechanically folded andformed and the candy packed therein, thereby dispensing with the manuallabor heretofore required in preparing the candy or articles for finaldistribution, with a resultvant decrease in the cost of production.

By the employment of the novel receptacle forming and filling machine ofour in-' vention the blanks are mechanically and automatically foldedand the receptacles filled or packed with a predetermined number ofcandy units.' The cand filled receptacles are then successivelydevivered onto or MINNEAPOLIS, MINNESOTA, NEAroLIs, MINNESOTA, A con-AND FILLING MACHINE.

may readily be removed and placed in shipping boxes to facilitatehandling in storage and transit.

Broadly, the'machine comprises a holder' in which a plurality ofreceptacle blanks are stacked, and from which the blanks aresuccessively fed to forming and intermittentl moving chain dies. As thereceptacle blank travels through the machine the various operations offolding the sides and ends thereof to form a receptacle areprogressively performed, and as the completed receptacle nears thedischarge end of the machine it is automatically filled or packed with aplurality of candy pieces or units, and finally discharged onto atraveling belt or conveyor, as hereinbefore stated.

The object of this invention, therefore is to (provide an improvedreceptacle-forming an filling machine of simple and practicalconstruction, which will be positive and efficient in performance.

Other objects of the invention will appear from the followingdescription taken in connection with the accompanying drawings.

Machine frame.

The frame of this novel receptacle-fium-A ing and filling machine ispreferably constructed of cast metal, and comprises a top plate.30, andthe front and rear walls 31 and 32, res ctively, as shown in Figures 1and 3. he two ends of the frame and also the bottom are preferablyopehl, as

shown, so that access may be had to the driving mechanism mountedtherein. Suitable legs 33 may also be provided for supporting the frame,or, if desired, these legs may be eliminated and the frame securedto atable or other supporting means.

Receptacle blank feeding mechanism.

The means provided for holding and feeding the blanks from which thereceptacles or cartons are formed, preferably consists of a holder orrack secured to the upper surface of the top plate 30 of the frameadjacent one end thereof, as shown in 'Figures 2 and 3. As shown inFigures 2l and 22, this holder or rack comprises a pair of rails 3lhaving wall members 35 secured to the upper portions thereof and towhich a plurality of upright guides 36 are secured by such means as thescrews or bolts 37. The rails 34 are supported upon the frame tpp 30 bymeans of shouldered studs 38 as s iown.

The form of blank used to make the typeof receptacle shown in thedrawings is represented in Figure 23. As here shown the main' body ofthe blank is preferably rectangular in form and each end is providedWith an outwardly extending central end-portion 39. A slit or cut 41 ispreferably provided on each side of the central end-portions 39 andthese slits extend into the body of the blank a distance substantiallyequal to the height of the walls of the receptacle when finished. Theblanks may also be scored as indicated by the dotted lines in Figure 23so that the material may more readily be bent in the formation of thereceptacle, as will hereinafter be described. In the actual operation ofthe machine, however, it has been found unnecessary to score the blanksto facilitate bend- 4ing, it being necessary only to provide the slits4,1 as shown.

Before starting the machine, the blank holder is filled with blanks asshown in Figures 2, 3 and 21. When the blanks are thus placed in theholder, it will be seen, by reference to Figure 2 that the centralendportions 39 of the blanks will be fitted between the opposed edges ofthe upright guides 36 and lwill outwardly project therebeyond. When thuspositioned, the ends or corners of the main body of the blank will alsobe fitted between the sides of the guides 36 thereby preventing theblanks from longitudinal or transverse movement, but allowing them todownwardly travel, as indicated by the arrow in Figure 3, to the feedslide as they are successively fed from the bottom of the stack to thereceptacle-forming-plungers and dies. The feed slide preferably consistsof a block 42 having oppositcly extending tongues 43 provided thereonwhich are adapted to slide in grooved guides 44 formed in the innerfaces of the two opposed rails 34, as particuthe length of these pins,the gap between the ends thereof and the faces 48 may be adlai-ly shownin Figure 22. The u per portion of the feed block 42 is provide with aninclined face 45 terminating in a shoulder 46 adjacent the central upperportion thereof. The lower corner 47 of the inclined face 45 preferablyextends slightly below the recessed faces 48 of the rails 34, whichfaces form the lower support for the blanks when the feed slide 42 is inits inoperative posi tion, as shown in full .lines in Figure 3 anddotted lines in Figure 21 (lefthandside of the ligure).

The two upright guides 36, adjacent the discharge end of the blankholder, referably terminate short of the recesse faces 48 of the rails34 so as to provide a gap 49 between the lower ends thereof and thefaces 48 through which the blanks may be. fed, one at a time, to theforming dies. The gap 49 must necessarily be slightly wider than thethickness of the material from which the blanks are made in order thatbut one blank may be fed therethrough at" a time. In order that this gapmay be varied or adjusted to suit the thickness of the blanks, pins 51are preferably provided in the lower faces of lthe two upright guides 36adjacent the discharge end of the blank holder as shown in Figure 22. Byvarying justed to allow f but one blank to be fed therebetween, and overthe formino dies at each forward movement of the feed slide or block 42.If the pins 51 are eliminated, the lower ends of the guides 36 must beso adjusted and spaced from the `faces 48 as to allow but one blank topass therebetween. If desired means may be provided for adjusting thewidth of the gap 49 to the thickness of the blank material. Such anadjust nient may be provided by vertically moving the guides 36 in thewall members 35 of the blank holders. The lower ends of the uprightguides 36 at the opposite end of the blank holder are referably seatedupon the faces 48 of the rails 34 so as to prevent any one of the blanksfrom being backwardly drawn with the fCed block 42 on itsreturn stroke.The rails 34 are preferably provided with forwardly'extendingend-portions 52,L as shown in Figure 21, to furnish a support for theblanks when fed over the forming dies, as indicated'by the dotted linesin the saine figure. .j l j v i The means provided for recirocallyactuating feed block. 42 .preferab y consists in the `provisionof an oscillating arm 53, pivotally mounted in a forked `bracket 54sesecured to the rear wall 32 ofk the frame. (Figures 2 and 3). 1 Aconnecting A"rod 55 connects the upper end of the oscillating arm" 53with the feed block 42 so that oscillation of the arm will impart areciprocal movement to the feed block 42. The connecting rod 55 ispreferably provided with means for adjusting its lene'th, as indicatedat 56, so as'to properly position the feed block 42 with relation to theblanks. 57 has one end connected, by means of a pin 58;' to the lowerend of the arm 53 and the other end of the connecting rod is mountedupon a crank pin 59 carried by a crank arm 61 secured to one end of ashort shaft 62 which is mounted in a bracket 63 secured to a suitablecross member 64 of the machine frame, clearly shown in Figure 1. A bevelA connecting rod pinion 65 is secured to the other end of the shaft v62and meshes with a similar pinion 66( mounted upon a shaft 67 rotatablymounted in suitable bearings 68 provided in the front and rear walls ofthe machine frame. (See Figure 3), The shaft 67 is driven from the maindrive shaft 69 by means of a pair of gears 71 and 72, as shown inFigures 1 and The drive shaft 69 is mounted in'similar bearings 73provided in the frame as shown in Figure 24.

In the operation of the feed block 42, the lower corner 47 of theinclined face 45 of the slide will project beneath the stack of blanks,when the feed block 42 is in normal "'or resting position, as shown infull lines in Figure 3 and dotted 'lines in Figure 21. When thuspositioned, one end of the stack of blanks will be resting upon theinclined face 45 of the feed block thereby slightly lifting or raisingthe lower blank out of contact with the blank supporting faces 48.

It will also be noted, by reference to Figure 3, that the shoulder 46,the height of which is slightly less than the thickness of the blankmaterial, will be out of contact with the lowermost blank. As soon,however, as the feed block starts its forward movement, the shoulder 46will engage the adjacent central end-portion 39 of the blank and willthereby forwardly move it, as indicated in Figure 2l. When thus beingfed forwardly by the feed block, the opposite end of the blank willpassbeneath the pins-51, and the blank will thus slide along upon theblank supporting faces 48 to the dotted line position shown in Figure21, and will remain in such position while the feed block 'returns -toits normal or starting position. As a result of the use of the inclinedface 45 of the feed block, the stack of blanks will be compressed at oneend thereof before the shoulder 46engages`the lowermost blank, while theopposite end of the stack will be relatively less compressed, therebypermitting the lower blank to be fed from beneath the stack with- -outdanger of buckling or bending. If desired. means may also be providedYfor limiting the forward movement of the blank to prevent it frommoving too far when fed provided in the head 79.

over um die backs 74 and 78 by the feed block 42, thereby positivelylocating the blank over the die blocks.

Receptacle forming mechanism.

The means provided for folding the blanks to form the receptacles orcartons preferably consists in the provision of a forming die 74 mountedabove the top plate 30 of the machine in spaced relation thereto. Asshown in Figures 5, 6, 7, 8, 9 and 10, this die is provided withoppositely extending lugs 75, 75, and 76, 76, and it is preferablysecured to the top of the machine by means of shouldered studs 77. Asshown in thc drawings the die block 74 in reality constitutes but oneside of the forming die as the other side thereof is constructed bymeans of a complementary die block 78, which is yieldably mounted in thehead 79 of a T-shaped bracket 81, having one end secured to the topplate 30 of the machine by means of a shouldered stud 82, and the otherend secured to a bracket 83 by a bolt 84. The bracket 81 is similarlyarranged in spaced relation to the top plate 30. It will be noted byreferring to Figure 5 that the bracket 83 is securely bolted to the topplate 30 by means of bolts 80.

As shown in Figure 8, the die block 78 is preferably yieldably securedto the head 79 by means of threaded studs 85 having one end securedthereto and the other end passing through sockets 86 and a ertures 87ompression springs 88 are mounted in the sockets 86 and threaded nuts 89are mounted on the threaded end portions of the studs 85 therebyproviding means for adjusting the diev block 78 with relation to itscomplementary die 74. By thus yieldingly mounting the die block 78, thecarton blank, when downwardly forced between the die blocks 74 and 78 bymeans of the reciprocally mounted plunger 91, will be firmly held inplace as shown in Figure 8.

The forming plunger 91 is mounted in an upright bearing 92 provided inthe horizontal portion 93 of the bracket 83, and has its upper endpivotally connected to an oscillating arm 94 by means of links 95. Theoscillating arm 94 is mounted upon a rock shaft 96 supported in bearings97 and 98 provided in the upper portion 99 of the bracket 83. Arelatively short arn'i 101 is mounted on the opposite end' of the shaft96 and has a connecting rod 102 pivotally connected thereto whichdownwardly extends therefrom through an opening 103 in the top plate 30of the machine and has its lower end operatively connected to a driv`ingl mechanism which will hereinafter be described.

In the operation of the receptacle forming dies 74 and 78 and theplunger 91, the

blanks are fed from the blank holder to the dotted line position,indicated in Figure 21, and the ful line position indicated in Figures 1and 7, in which position the blank will be inter osed between the dieblocks 74 and 7 8, an the lower face of the plunger 91, and will besupported upon the end portions 52 of the rails 34. As the plunger 91 ismoved downwardly, by the oscillating arm 94, the blank will be forcedbetween the two die blocks, to the position shown in Figure 6. When theplunger 91 moves from the position shown in Figures 1, 3, 4 and 21, theblank will be lon itudinally bent or folded along the dotted mes a, a(Figure 23), thereby forming the opposed side walls of the receptacle,and thus completing the first operation in its formation. As soon as theside walls have thus been formed, and the lunger 91 reaches the positionshown in igure 6, the downward movement of the plunger will betemporarily interrupteduntil the second forming operation has beencompleted. The second forming operation conslsts in inwardly bending thecorners b of the side walls, along the dotted lines c to partially formthe ends of the cartons. (Figure 23).

The means provided for inwardly bendin the corners, or ends b of one ofthe si e walls, to partially form the ends of the receptacle, preferablyconsists in a pair of rods 104, reciprocally mounted in bearings in theopposed lugs 75 and 76 of the die block 74. These rods are connectedtogether at one end by a cross bar 105 as shown 1n Figures 2 and 5. Thiscross bar is engaged by a cam 106 upon the upper reduced end portion 107of a vertical shaft 108, (Figure 1) mounted in a suitable bearing 109provided in the top of the machine frame.

ompression springs 111 are coiled about the rods 104 and function toyieldably hold the bar 108 against the face of the cam 106,

collars 112 preferably being secured to the .rods 104 to engage one endof each spring while the opposite ends of the springs are adapted tobear against the lugs 75 of the die block 74, as shown in Figure 5. Therods 104 function to inwardly bend two of the corners or ends b of oneof the side walls as hereinafter described.

A pair of L-shaped rods 113 are also mounted in the opposed lugs 75 and76 of the die block 74, adjacent the outer ends thereof, as shown inFigure 5. These rods are similarly connected to ether at their outerends by means of a yo e 114, which is adapted to engage a cam 115, alsomounted on the upper reduced end-portion 107 of the upright shaft 108.Similarly, the yoke 114 is yieldably held in contact with the cam 115 bymeans of springs 111 and collars 112. The rods 113 are provided withinwardly projecting end portions 116, having curved ends 117 adapted toengage the ends b of the other side wall when the rods are actuatedbythe rotation of the cam 115.

In the operation of the rods 104 and 113 'the upriht shaft 108, which isoperatively connecte to the driving mechanism mounted beneath themachine top 30, will be rotated, causing the cams 106 and 115, mountedon the upper end thereof, to be rotated also with the resultantactuation of the rods 104 and 113. Referring to Figures 5 and 9, it willbe noted that as the cam 106 is rotated, as indicated by the arrow inFigure 5, the rod 104 will be moved towards the partially completedreceptacle positioned between the die blocks 74 and 78. Such movement ofthe rods will cause the ends. thereof to engage the corners b of one ofthe receptacle side walls with the result that the ends will be bentalong the dotted lines c, shown Vin Figure 23, and around the ends ofthe plunger 91 as shown in Fi res 5 and 9. Before the rods 104 starttheir return movement ther rods 113 will commence to move forwardly sothat the curved ends 117 thereof will engage the ends b of the otherreceptacle side wall and will bend them inwardl'y as shown in Figures 5and 10.' As soon as the corners b, engaged by the curved ends 117 of therods 113, reach substantially the osition shown in Figure 5, the rods104 wil be retracted, thereby allowing the curved ends 117 to fold theopposite or outer corners ZJ over the inner corners, as clearly shown inFigure 10. As soon as the corners b have thus been folded or bent tooverlap one another the plunger 91 will resume its downward movement andwill thereby force the partially completed carton or receptacledownwardly from the position shown in Figures 5 and 6 into one of thepocket dies of a movable chain die (see Figure 11), which will next bedescribed. When the receptacle is thus forced into the movable chain diethe oppositely extending end-portions 39 of the blank will be upwardlybent along the dotted lines d (Figure 23) tothe position shown in fulllines, Figure 11, and dotted lines, Figure`13.

M ovable chain dies.

Figures 27, 28, 29 and 30, show in detail the construction of themovable chainv die employed in conjunction with this novel machine toprogressively and intermittently move the cartons or receptacles throughthe machine, as the various operations in the tion. Each chain is alsopreferably mounted so as to be in 'direct contact with the upper surfaceof the machine top 30, (Figure 29), so that the weight of the two chainswill becarried directly by the top plate 30, and not by the sprockets.Also, by this arrangement the plate 30 will form the bottoms of the diepockets formed between the adjacent arallel sections of the two chains,as will su sequently be described.

Each belt or chain preferably comprises a plurality `of similardie-forming members or blocks 121, alternately arranged in the chains,and each such member having an outwardly extending blade 122 adapted tocooperate with the blades of adjacent blocks to form the side walls ofthe die pockets, as particularly shown in Figure 27. In this figure itwill be noted that a series of lsuch die pockets are formed between theadjacent sections of the two chains, the blades 122 froming the sidewalls of the die pockets and the blocks 121 the ends thereof. As shownin Figures 28, 29 and 30 the central portion of each die-forming memberor block 121 is preferably cut away to provide a channel or groove 123adapted to receive the connecting means provided for pivotallyconnecting or linking together the blocks 121. The blocks 121 of thechains are connected together by means of spaced arallel links 124 andpins 125 Ipreferably having their ends headed over and seated incountersunk seats, as shown in Figure 29. Anti-friction rollers 126 arepreferably interposed between the spaced connecting links 124 adapted toengage the opposed bars or rails 120 to prevent the` adjacent sectionsof the two chains from spreading when the receptacles are being formedin the die pockets provided therebetween by the blocks 121 and blades122. The rails 120 may be secured to the top plate 30 of the machine bysuch means as the bolts l or screws 127. In Figure 27 there is shown inthe movable chain die pockets, the relative positions of thereceptacles, and the result of each forming operation as the receptaclesprogressively and intermittently advance through the machine in theformation thereof.

For intermittently actuating the movable chain dies we preferablyprovide an interv mittent driving mechanism commonly known in mechanicsas a Geneva stop movement.

As shown in Figure 27 the drive sprockets l 118 are secured to the upperside of a air of upright shafts 128 rotatably mounte in suitablebearings provided in the top plate 30 of the machine frame (Figures 2, 5and 24). The bearings 129 are here shown as formed integral with the topplate 30, but it is to be understood that, if desired, these bearingsmay be constructed independentli7 of the machine frame and securedthereto by suitable means. Spiral gears 131 are "ecured to the lowerends of the upright as shown in Figures 4, 25, 26 and acomplef isk 137mountedon the drive shaft 69. A drive pin 138 is secured to the' mentarydrive `disk .137 adapted to en age the ra'digl slots 136 to rotate thewhee 135 when t 137 is rotated. (See Figure 25). A khub 1,39 is providedon one side of the disk 137 in alinement withthe. face of the slottedwheel 135. The hubjis adapted to engage correspondingl curved faces 141rovided between the ra ial slots in the whee to lock said wheel againstrotation when the drive pin 138 is out of engagementwith the slots 136as shown in Figure 26. A portion of the hub 139 is cut away to provide aface 142 shown in Figures 25 and 26, to provide l clearance for theslotted wheel 135, when belco ing rotated by the pin 138 (Figure 25). U

In the operation of the intermittent drive mechanism above described,the slotted wheel 135 and therefore the shaft 133 will be rotatedone-eighth of a revolution for each revolution ofthe drive shaft 69.When the wheel 135 is in locked position, it will be 'powheel. Asthedisk 137, and therefore the pin 138 and hub 139, continue to rotate, thepin will engage the next slot in the wheel, as indicated by the dottedlines in Figure 26, and will thus commence to rotate the wheel. It is tobe uderstood, of course, that when the pin 138 engages the next slot136, 'the clearance face 142 of the hub 139 will be moved to the dottedline position in Figure 26, in which position the wheel may be rotatedby the pin as shown in Figure 25. In thedrawin we have shownthewheel 135as having eltght driving slots, but it is to be understoodl iat thenumber ofslots maybe varied as desired, to increase orV decrease theintermittentv travel of the movable chain dies. v

Referring to Figure 27 it will be noted that the idler sprockets 119, suporting one end of each chain, are rotatably mounted upon studs 143secured to the top plate 30 of the machine frame. If desired, thesestuds may beA adjustably mounted in the frame so as to rovide means fortaking up slack in the chains, caused by wear, etc., and they may bealsoso arranged as to be adjustable to and from each other to provide meansfor slightly varying the lengths .of

e disk the diepocket's, composed vofthe adiacentv 65 sections of the twochains.l

AAfter the partially completed carton or receptacle has been downwardlymoved from p in Figure 1l, it will'advance to the osi-,

tion shown in Figure 12, where it wi be engaged by means for inwardlyand down- -wardly folding or bending theI upstanding @centralend-'portions 39 thereof' tofcomplete).

the forming operation of -thecartom 'f he means provided for inwardlyand down wardly bendingl theend-portion 39 lof. the incompleted cartonis clearly-l shown. in Figures 12` 13A and 14. As here shown such meanspreferably consists in the provision of a pair of pivotallymountedcurved fingers 144 upwardly projecting lthrough, elongatedapertures 145 provided in the machine top 30, and adapted to have theirends swing.

over the incompleted carton as shown vin Figures 12 and 13. Each finger144 has an integral hub 146 which is apertured to receive a stud 147 toprovide a pivotal mounting therefor. The studs 147 are preferablysecured to a block 148 secured to the underside of the machine top 30,by suitable screws 149 Figui'e 6). Each hub 146, has a de ending oss 151adapted to receive a shoul ered'stud 152 upon which a roller 153 ismounted. A tension spring 154 has its ends 'secured to lugs or earsprovided on the dependingbosses 151. and this spring functions toyieldably hold theI rollers '153 in contact with the opposedfaces of apair4v of 'cam disks4 155, mounted on the drive shaft 69. (See Figure13). Each cam disk 155 has a raised portion 156 adapted to engage therollers 153 and outwardly move them to the position shown inl Figure 13, when the disks 155 are rotated.A Such outward movement of the rollers153 will cause the upper curved ends of the fingers 144 to be moved from`the dotted to the full line position shown in Figure 13, which actionwill causethe terminals of the fingers to engage the upstandingend-portions 39 of the carton and inwardly and downwardly fold or bendthem 'from the dotted line position shown in Figure 13', to the. fullline position shown in Figures 12 and 13. After the ends 39 have thusbeen inwardly folded, the incompleted carton will be automatically andprogresively advanced in"th emac'hine from the position shown inFigures12 and 13, to the position indicated at A in- Fig,-

' later.

gage thel upper portion of the die chains, as shown in Figures 5 and 6.This plate functions to retain the end-portionsy 39 of the cartonsinfolded position, while the carton is being moved from the positionshown. in Figures 11, 12 and 13 to that shown 11n .Figures 6l and 14.

te the position shown -in Figure 14. The

function of the plunger 157 is to downwardly fold the inwardly extendingendportions 39 from the position shown in Figure 13, to that shown inFigure 14. This punch also functions to square the walls of the cartonso that whenl completed it will resemble the receptacle shown in Figure15.

The upper end of the die shank is secured to a suitable cross head 158,which is plvotally connected.I by means of links 159, to an oscillatoryarm 161, similar l.in construction and function to the arm 94,previously described. The arm 161 is mounted on a rock-shaft 162 mountedin the upper portion 99 of the bracket 83. A relatively shorter arm 165is mounted on the opposite end of the shaft 162 and has a connecting rod164 pivotally connected thereto which depends therefrom through anaperture 165 in the frame top 30. 'The lower end of the rod 164 isoperatively connected to a suit able driving means which will bedescribed Receptacle filling mechanism.

The means provided for filling the receptacles or cartons with candy orother material, and also the means provided for feeding the candy to thefilling mechanism, is plainly feed tray 166, mounted adjacent one sideof.

the machine, upon a suitable supporting means, not-shown. This feed trayis preferably provided on three sides with marginal upturned flanges167, 168 and 169, which function to retain the candy units thereon aslthey are manually fed over the surface of the tray. Each candy unit,before being placed on the feed tray 166, is usually wrapped in waxedpaper for sanitary purposes, as the form of receptacle here used is ofthe open type, as shown in Figure 15, and therefore does not offer anyprotection to the candy when packed therein, as shown in Figure 20.After 4the candy has thus e horizontal portion 93 of the bracket beencut into small units and preferably wrapped, as above stated, which isusually done by automatic machinery, it is placed uponthe tray 166 andarranged in rows, as4

.shown in Figure 2.A The operator will then placev thetray upon asupporting means adjacent the; machine and manually feed the candyacross -the surface thereof, inv the direction of the arrow, until theleading row is brought into contact with the upturned `fla1ige1-68,after which it is fed transversely across thetray through an opening 171and into a feed' chute 172, as indicated by the arrow. The feed chute172 extends over the top of the machine and has its dischargeendterminating at a' point directly above thc completedreccptacle, seatedin one of the .die pockets, composed of the two chains.

(See Figures 16,- 17, 18 and 19)..'

` shown in Figure '16, the feed chute 172 is preferably supported uponthe machine top 30 by means of a shouldered stud 173, and is arranged inspaced parallel relation thereto so as to overhang the die pockets. Anelongated discharge opening 174 4is provided adjacent the' end of thcchute, and this opening is in vertical alinement withI the emptyreceptacle positioned therebeneath in oneQ of the .die pockets. (Figure16). An adjustable stop plate 175 is .mounted adjacent the end of thechute. Anadjusting screw `176having.; a knurled head 177, is mounted ina threaded aperture provided in the end wall 178 of the-chute. One endof the screw 176 is preferably turned down, as shown, to provide areduced end portion 179 which is rotatably mounted Iin'an apertureprovided in the` stop plate 175,` and is slightly headed over so as toprevent it from becoming disconnected therefrom. A lock nut 180ismounted on the screw 176 to lock it in adjusted position. The 4stopplate 175 functions to provide a stop for the candy as it is fed intothe chute so that it will be in direct alinement with the dischargeopening 174 and the empty receptacle positioned thcrebeneath.

Referring to Figures 16, 18 and 19, it will be noted that the candyunits, when positioned in the chute over the discharge open ing 174 andagainstvthe stop plate 175, will be prevented from dropping therethroughby means of a pair of yieldably mounted gates 181 which are adaptednormally to partially close the discharge opening 174, as indicated bythe dotted lines in Figure` 18 and by `full lUU lLU

lines in Figure 19. These gates aremounted A ing them into the carton,prefers. ly consists of a packer plunger or ram 185 mounted 1n Va.vertical guide bearing provided in the bracket 93, direct-l7 above thechute 172. The upper end of tii the cross-head 158, as shown in Figurel, so Vthat it will be o erated each time the cross-head is aetuate bythe timed oscillation of the arm 161. 'lhus it will be seen that eachtime the cross-head 158 is actuated, the packer plunger 185 will bedownwardly moved from'the position, shown in Figure 16, into contactwith the candy units positioned in the chute directly beneath. (Figure17). As the plunger continues in its downward movement it will force-theunits through the discharge opening 174 and against theyieldably'mounted gates 181, .which gates will thereby be opened to thefull line position in Figure 18, and allow the candy to be inserted oracked into the re ceptacle as shown in igures 17 and 18. When the candypieces or units have thus been packed into the receptacle, the packerplunger 185 will be returned to normal position as shown in Figure `16.A guide plate 186 is preferably secured to one end of the packer plungerto prevent the candy, remaining in the chute, from falling over onto theplunger when in the osition shown in Figures 17 and 18. A at spring 187lis also provided to frictionally hold the candy unit in an uprightposition in the chute when the units at the end of the chute are beingpacked into a carton. This spring is preferably secured to a bridge bar188 mounted over the chute (see Figures 16 and 17).

Means are also provided for retaining the end candy units in an uprightposition in the chute each time the candy is manually fed along in thechute after the pieces or units at the end of the chute have been packedinto a. receptacle. Such means preferably consist of a' tension plate189 secured to one Thus it will rea ily be seen that .by the use of thistension plate the candy lmits will be frictionally held in an uprightposition while being fed along'the chute over" the discharge opening174. The tension plate 189 is adjustabl and yieldably mounted on thewall of t e chute bv means of threaded'studs 192, secured to the wall,

s plunger is secured-tov and having lnurle'd 'adjusting nuts 193 mountedthereon. A compression spring 194 is mounted on each stud between theplate and the adjusting nuts so that the pressure of the plate againstthe candy may be varied or adjusted to the proper degree. Guide rollers195 are also provided at each end of the discharge opening 174 to guidethe units linto the empty receptacle (sec Figures 16 and 17).

After the candy has been packed into the receptacle, as above described,and as shown in Figure 20, the intermittent drive mechanism will causethe die chains tovbe actuated which will move theilled receptacle fromthe position shown at B in Figures 5 and 27, to the position shown at Cin the same figure?. lVhen in the latter position the receptacle will bemoved in registration with an opening 196 provided at the end of themachine top30, as shown in Figures 1, 2, 4 and 6, and Will thence dropinto a curved discharge spout 197 and be discharged onto a suitableconveyor belt 198, having one end mounted on a drive roller 199, carriedby al shaft 201 which is rotatably mounted in bearings 202 and 203,provided in the side walls 31 and 32, respectively, of the machineframe. Thev other end of the conveyor belt 198 may be supported bysuitable means, not shown. the filled receptacles will be dischargedonto the conveyor belt 198, as shown in Figure 1, and may then beremoved therefrom and packed into larger cartons or shipping boxes tofacilitate handling in storage or transit.

A plunger or ejector 200 is preferably provided adjacent the packerplunger 185 to positivel eject the filled receptacles from the chain diepockets into the curved chute 197. This ejector is mounted on the crossIn the operation of the machine head 158 and depends therefrom in spacedparallel relation to the Dm'vnlg mechanism.

The driving mechanism of this novel receptac'le-making and fillingmachine is shown in Figures 1, 3, 4 and 24. As shown in Figure 24 a.pulley 204 is rotatably mounted on the drive shaft 69 between a. collar205, secured to the shaft, and a flanged coupling member 206 slidablymounted on the shaft and prevented from rotation thereon by a. featherkey 207, secured to the shaft. A collar 208 is secured to the outer endof the shaft to 'provide a stop for lthe coupling member 206 when movedout of engagement with the pulley 204. Pins 209 are provided on thecoupling member adapted to be received in suit-able apertures providedin the web of the pulley, thereby to transmit power from the lpulley tothe shaft when the coupling member is positioned as shown in Figure 24.When the coupling iiient with the pulley and the latter willbe fi'ee torotate or idle on the shaft.

The cams 106 and 115, actuating the carton end-folding 4fingers 104 and113, are driven from a cross shaft 211 mounted in bearings provided inthe front and rear walls of the frame. (Figures 1, 4 and 24) A bevelpinion 212 is secured to this shaft and meshes with a similar pinion213, terminally mounted'oii the vertical shaft 108 as shown in Figure 1.A sprocket- 214 is mounted on the shaft 211 adjacent the rear frame wall32 and has a chain belt 215 operatively connecting it with a similarsprocket 216, mounted on the drive shaft 69 (Figure 24). Thus it will beseen that whenever the drive shaft 69 is rotated the cross shaft 211will also be rotated with the resultant actuation of the cams 106 and115, and therefore the end-folding fingers 104 and 113. Referring toFigure 6 it will be noted that the cams, and also the cross bars 105 andyoke 114, are preferably arranged in staggered relation, so that the cam106 will engage only the cross bar 105 and p will clear or swing overthe yoke 114, and,

similarly the cam 115 will engage only the yoke 114. The cams 105 and115 are also so arranged on the shaft 108 that the fingers 104 and 113will be actuated in timed relation lto the movement of the die chainsand the rest of the mechanism.

The mechanism provided for operating the connecting rods 102 and 164 toactuate the rock shafts 96 and 162, and therefore the plungers 91, 157,185 and 200, preferably consists of a grooved cam member or wheel 217mounted on the lower transverse shaft 67 (see Figures 3 and 4). This camwheel has a cam groove 218 formed in one side or face thereof adapted toprovide a track for an anti-friction roller 219, mounted on anoscillating arm 221, which is mounted on a rod 222 journaled in the sidewalls of the frame. A forked bracket 223 is pivotally connected to theend of the arm, and this bracket has the lower end of the connecting rod102 slidabliy mounted therein". A collar 224 is termina ly secured tothe rod, and a compression spring 225 is interposed between this collarand the up er portion of the bracket so that the r will have a yieldableconnection with the arm 221. A stop collar 266 is also secured to therod 102 above the bracket 222 to limit the movement of the rod withreference to the bracket. Thus when the cam wheel 217 'is rotated, thegrooved cam 218 will cause the arm 221 to be oscillated, which willtransmit a rocking movement to the rock shaft 96 as a result of it beingoperatively connected thereto by means of the connectin rod 102 and arni101. Such rocking of t e shaft will-cause the forming plunger 91 to beactuated in the initial formino` operation of a receptacle, as hasherein efore been described. The cam groove 218 is so shaped as to causethe downward movement of the forming plunger 91 to be interru ted whenit reaches the position shown in igure 6, thereby allowing thereceptacle end-forming lingers 104 and 113 time to inwardly fold theends of the carton blank, after which the cam will complete the downwardmovement of the plunger, moving it from the position shown in Figures 6,8, 9 and 10 to that shown in Figure 11, wherein it will be noted thatthe partially completed carton will be seated in one of the die pocketsof the die chains.

. A cam groove 227, of a relatively different shape than the groove 218,is provided on the opposite face of the cam wheel 217, and functions toact-nate the connectin rod 164. The means provided for operativelyconnectin the rod 164 with the cam groove 227 is simi ar in constructionto that shown and described with reference to the other rod 102 and camgroove k218, and like parts will therefore be indicated by likenumerals. As shown inv Figure 4, the cam groove 227 andoperatingmechanism functions to operate the connecting rod 164, whichwill cause the rock shaft 162 to be oscillated with the resultantactuation of the cross-head 158, and therefore the punches 157 185v and200, as has been previously described. It is to be understood that theloperation of the punches 91, 157, 185 and 200, by the cam grooves 218and 227 must be in timed relation to the intermittent movement of thedie pockets, formed by the two endless chains, in which the cartons arepositioned as they advance through the machine in the formation thereof.The lower transverse shaft 67 is driven from the drive shaft 69 by theintermeshing gears 71 and 72, as hereinbefore described. (See Figures 1and 3).

The means provided for operating the conve or belt 198 is shown inFigures 1 and 4, an particularly in Figure 24. Referring to the latterfigure, a sprocket wheel 228 is operatively connected to a similarsprocket 229 by means of a chain belt 231. The sprocket 229 ispreferably mounted upon and secured to a hub 232 of a pinion 233,rotatably mounted on a stud 234 secured to an arm or bracket 235. Thebracket 235 has a split hub 236 which is adjustably mounted upon the hubof the bearing 203, supporting one end of the shaft 201. A bolt orcap-screw 237 is provided in the split hub 236 to lock it yin adjustedposition. A pinion 238 is mounted on the conveyor shaft 201 and mesheswith .the pinion 233, mount- .ed on the stud 234. Thus it will be seenthat iio
